TWROVEMENT 1H APPARATUS FOR RAISING LOWBRING- CHANDELIBRS AND LAMPS.

The Schedule referred to in these I ettera Patent and making part of the same To all whom it may concern Be it known that I, HENRY S. HALL, of Boston, in the county of Sufl'olk, and State of Massachusetts, have invented a new and improved Apparatus for Raising and Lowering Chandeliers or other fixtures,

of which the following is a full, clear, and exact de-' scription', reference being had to the accompanying drawings, in which- 1 Figure 1 represents a front elevation, with the face plate removed.

Figure 2 is a section of details.

The same letters refer to the same parts in the different figures.

vThe object of my invention is to produce an apparatus by which chandeliers, suspended lamps, and other fixtures, can be raised, lowered, and held firmly in position, in a simple and efficient manner, without the use of weights, pulleys, cords, or springs; and

My invention consists in applying the weight of the chandelier, lamp, 850., to act, by means of the rod or tube to which they are attached, on two levers, pivoted to the upper portion of said rod or tube.

To one end of said levers are secured two elastic and corrugated friction-rollers. The other end, which projects beyond the pivot, reaches under 't'nut, which thus regulates the tension of the friction-rollers,

Referring to the drawings- A is aframe, attached, at its upper portion, to the ceiling, by mean's'of rod B. p

The lower portion is provided with an aperture, through which ,passes the rod or tube 0, to the lower end of which is secured the chandelier, lamp, or other fixture.

Against the shoulder of the upper portion of rod 0, rests the collar 0. r

The small end of rod 0 is provided with screw threads, to receive nut D. I v

The collar a is provided with two arms, to which are pivoted the curved levers b b, the shorter ends of which pass underneath nut D, while to the longer ends are" secured the friction-rollers c 0, respectively, which run against the corrugated guides 11 d of frame A..

Two face-plates, of which one only is shown in the Operation. Suppose the chandelier being in such aposition as is indicated by rod 0, in relation to frame A. The ,7 weight of the chandelier, acting upon the pivots and levers b b, throws the outer arms, to which the rollers .cv care. attached, against the guides at the inner side of frame A, and exerting a pressure against the latter, corresponding to the weight of the chandelier or fixture, and thus holds the latter at any desired height within the frame.

1n loweri ng the chandelier, loosen the nut D sufi'iciently to reduce the tension against the guides, and pull downward. In raising the chandelier, push it simply upward.

By setting the nut D in the proper position, the

whole operation "can be performed without loosening or tightening the nut at all, which latter operation I will only become necessary when the wearing oil of the rollers c 0 should require more tension. 4

Having thus described my invention, What I claim as new, and desire to secure by Let,- ters Patent, is-- v The frame A, in combination with rod 0, levers b,

corrugated rollers c c, and nut D, constructed in the manner and for the purpose substantially as described. In testimony whereof, I have signed my name to this specification, in the presenceof two subscribingwitnesses.
